摘要:
A surgical instrument is disclosed. The instrument includes an end effector comprising a moveable cutting instrument to cut an object and a motor coupled to the end effector. The motor actuates the cutting instrument in response to a current therethrough, causing the cutting instrument to move between a proximal-most position and a distal-most position. The instrument includes an interlock coupled to the end effector and to the motor to prevent actuation of the cutting instrument based on the current through the motor.
摘要:
A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.
摘要:
Various forms of surgical instruments are disclosed. In various embodiments, an end effector having operable and closable jaws is attached to a distal end of an elongate shaft such that portions of the jaws are axially offset from the elongate shaft. Other jaw embodiments are coupled to an actuation arrangement that permits portions of the jaws to be moved out of axial alignment with the elongate shaft. Other jaw embodiments are configured to facilitate tissue dissection. Electrosurgical instruments are also disclosed. One embodiment employs a flexible electrode that is conformable to tissue.
摘要:
An assembly including a component of a surgical instrument, such as an endoscopic or laparoscopic instrument. The assembly may comprise a package; a surgical instrument component within the package; and a power source within the package. The power source may be configured to be placed in electrical communication with the surgical instrument component. The assembly may also comprise an auxiliary power source within the package and a circuit element, where the circuit element is in electrical communication with the power source and the auxiliary power source.
摘要:
A surgical instrument is disclosed. The surgical instrument includes a control unit and a staple cartridge including a transponder. The control unit is configured to transmit a first wireless signal to the transponder and to receive a second wireless signal from the transponder to determine one of a first electronic state and a second electronic state of the transponder based on the second wireless signal.
摘要:
A surgical cutting and fastening instrument. The instrument comprises an end effector, a shaft connected to the end effector, and a handle connected to the shaft. The handle comprises an electric, DC motor connected to a drive train in the shaft for powering the drive train. The handle also comprises a power pack that comprises at least one charge-accumulating device connected to the DC motor for powering the DC motor.
摘要:
An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue thereby causing current to flow through the tissue and, as a result, generate heat within the tissue. The surgical instrument can further comprise a fluid circulatory system embedded within at least a portion the end effector wherein, in at least one embodiment, the fluid can be dispensed from the fluid circulatory system and onto the jaws of the end effector and/or the tissue positioned between the jaws.
摘要:
A surgical instrument, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector comprising at least one sensor. The surgical instrument may also comprise an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft. The surgical instrument may also comprise a handle connected to a proximate end of the shaft. The handle may comprise a control unit electrically coupled to the shaft such that the shaft radiates signals as an antenna from the control unit to the sensor and receives radiated signals from the sensor. Other components electrically coupled to the shaft may also radiate the signals.

摘要:
A surgical instrument, such as an endoscopic or laparoscopic instrument, comprising, according to various embodiments, an end effector comprising at least one sensor transponder. The surgical instrument also comprises a shaft having a distal end connected to the end effector and a handle connected to a proximate end of the shaft. The handle comprises a control unit in communication with the sensor transponder via at least one inductive coupling. The surgical instrument may be a power-assist motorized device including a battery for powering (at least partially) the surgical instrument during use. The surgical instrument may be adapted to provide user feedback regarding the load being experienced by the end effector.
